Download and install Android Dev Preview for Pixel XL.Android O but we’re really hoping it’ll become Android Oreo once it’s released).Introduces a number of new features and APIs to use in your apps. Here's are just a few new things for you to start trying in this first Developer Preview.

For the second year in a row, Google is making a developer preview for the next version of Android available in March, well ahead of its presumed consumer release in the fall. This one is codenamed “O,” and your guess is as good as mine as to what dessert the final version will be named after. It isn’t yet available for regular users to try out. Although developers can begin testing it right away, it’s best for most people to let things stabilize a bit more before they try it out. Developers can download it today.

How to install Android O Dev Preview on Pixel XL:

Download the Android O image for Pixel XL below, then unzip it to a safe directory.

Connect your device to your computer over USB.

Start the device in fastboot mode with one of the following methods:

Using the adb tool: With the device powered on, execute:

adb reboot bootloader

Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 ("hammerhead") into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.

If necessary, unlock the device's bootloader using one of the following methods:

If you are updating a Pixel XL or Pixel XL device using the hammerhead or angler builds, update your fastboot tool to the latest available version (>=23.0.1), and then run this command:

fastboot flashing unlock

If you are updating an older device, run this command:

fastboot oem unlock

The target device will show you a confirmation screen. (This erases all data on the target device.)

Open a terminal and navigate to the unzipped Android O image for Pixel XL.
